The sense of smell plays an important role in everyday life, for example in food, beverages, perfume and hygiene. For many animals the sense of smell is their primary sense to experience their world. But still, we have no clear understanding of how odors are perceived. Moreover, while we readily understand how to describe visual stimuli with light wavelengths and contrast, or sounds with frequency and amplitude, we lack understanding of the fundamental features of odors. In other words, we don't understand Odor Space .
